CURTAIN-CORD TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 275,303, dated April 3, 1883.

Application filed May 2, 1882. (No model.)

To all whom it may concern Be it known that I, FRANCIS J. WERNETH, of Baltimore city, State of Maryland, haveinvented certain new and useful Improvements in Curtain Cord Tighteners; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which- Figure l is a front elevation of the device; Fig. 2, a central longitudinal sectional View, and Fig. 3 a similar view of a modified form of the device.

My invention relates to devices for maintaining a proper tension of the cords of window-curtains; and it has for its object to produce an article of that class of superior eflimade.

In the drawings, A is a sheet-metal plate, having perforated end tangs for the attaching tacks or screws 6, the sides a of the plate being folded over, as shown. In the back is stamped up, in the act of punching the plates from the sheet, a ratchet, D. The ends a ofthe sides a are rounded, in order to facilitate the insertion of the sliding block B and to prevent injury to the hands in drawing down the curtain-cord. TheblockBisslottedorgrooved at the side, and slides on the edges of the sides a. It is provided with a rounded knob or pulley, c, for the cord, and has pivoted at f a catch, 71, provided with a lip to engage with catch is turned upward, serving to admit of its retraction to disengage its point from the ratchet. The modification shown in Fig. 3 differs from this only in having the spring and catch made in one piece and riveted on the under side of the block B.

The base-plate is cheaply struck up, the ratchet being formed and the ends perforated at one operation. The block B may be cast, and the catch is simple in construction and readily applied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with the plate A, having struck-up ratchet and folded sides a, with rounded ends a, the sliding spring-catch B b, as set forth.
